• HSBC Report: “The Capacity Crunch”, 2009

• AT&T/3G Americas Report, 2009

• Cisco’s Global Mobile Data Traffic Forecast, 2010

• Report from EC, 2008

The long-awaited wireless data exponential growth is underway: can we handle it?

“The iPhone is just the vanguard, with applications and content growing richer and with ever more sophisticated devices”

Mobile data to increase 40-fold between 2009 and 2014, reaching 3.6 Exabytes (2/3 video)

According to HSBC, the future sources of additional capacity are:

• More bandwidth (analog TV, new spectrum at 2.3 and 3.4 GHz)

• Offloading onto wireline via femtocells or WiFi.

• Increased cell density, at the expense of: Site procuring (permits, radiation, civil engineering) Network planning Backhaul & other operational expenses

“There is no more low-hanging fruit for the mobile industry in terms of spectral efficiency gains to drive network capacity”

• Network MIMO (or CoMP, “Coordinated Multipoint Tx/Rx”, in LTE parlance)

• Interference alignment

• Relays

• Femtocells

• Huge numbers of antennas
